Ooops,
I already expected, that there would be another way, because it seems to
be a quite useful function, not only for heightfields.
Anyway, code is in p.t.s-f.

You're making one rather large assumption there...
You're assuming that everybody uses MegaPOV, since AFAIK, trace() isn't
yet an official POV function :)
I still use plain old 3.1g on the grounds that if I ever get a scene I
feel is worth releasing the code for, then I don't want people to be
unable to trace it just because they haven't downloaded a patched version
of POV.
Bye for now,
Jamie.

Yeah, how true. I've been persuaded very much into the realm of <commanding
echo>MegaPov</commanding echo>.
Although, Christopher's hf_normal_at macro is also using it :-)

Would have been quite a lot of work manually reading the height file...
I don't see anything wrong using megapov if it helps making things
easier and/or better. Of course it is difficult to download for those
who only have slow internet connection.
<small try>
And somewhere along the way there will be Version 3.5... ;-)

Nay, 'tis but just a mere 3/4 megabyte or there abouts. If I had only a 14.4K
modem I'd have gotten it anyway (oh, I do have a connection near to that :))
The anticipated POV-Ray 3.5 will most certainly be a couple megabytes or more
if history proves to be repeated.

Whoa, terribly sorry! I only just now realized what you were doing by saying
this part. I thought you were angry at the "a lot of work" thing. Somehow I
completely skipped over what you had said. And I swear to you I was seeing
Christopher written/signed everytime. This might mean I'll need to start
wearing my glasses at home. Oh I hope not.
Let me try this now... <practice> Christoph </practice> There, I did it.
Yea!

Don't worry about it, you are not the first one to make this mistake...
AKAIK Christoph is not a very common name in english speaking countries,
so if anybody feels irritated i would prefer Chris to Christopher.
Concerning the question of official/unofficial version, I think it is
mostly a question of standards and compatibility.

Neither is hf_height_at, which the macro uses.

Whoops. You can tell I don't do much in the way of hand coding scenes,
can't you :) (that, plus the fact that I haven't actually looked at the
code in any way other than to see that it scared me :)
I wonder if it would be possible to do anything even remotely similar
using plain old vanilla POV 3.1g though?
And I shall say again what I have said before. I have the programming
skills of a Woodlouse <grin>.
Bye for now,
Jamie.

Oh, that one is really harmless ;-) , you should take a look at some
parts of the Pov-source...

The only way I see is to read the HF-file with Pov's file I/O routines,
that would only function with ASCII files (for example PGM) and would be
extremely slow with usual HF-sizes.

programming is much fun, so you should really try it.
